IMPROVEMENT IN GANG PL OWS.

Specification forming part of Letters Patent No. 48,696, dated July 11,1865.

To. all whom it may concern:

Be it known that we, J. H. LA BOY'IEAUX and O. A. ASHTON, both ofJacksonville, in the county of Morgan and State of Illinois, haveinvented a new and Improved Gang- Plow; and we do hereby declare thatthe following is' a full, clear, and exact description thereof, whichwill enable others skilled in the art to make and use the same,reference being had to the accompanying drawings, forming part of thisspecification, in which- Figure 1 is a side sectional view of ourinvention, taken in the line or 00, Fig. 2; Fig. 2, a transversevertical section of the same, taken in the line 3 y, Fig. 1.

Similar letters of reference indicate like parts.

This invention relates to a new and improved means for raising the plowsout ofthe ground when required, and also for adjusting the same so thatthey may be made to work in a proper relative position with the groundwhen the latter has an inclined or uneven surface.

A represents an axle, to one end of which apendant, B is attached,provided at its lower end with an arm, 0, on which a wheel, D, isplaced. The opposite end of the axle is provided with a socket, E, inwhich an upright, I, is fitted loosely, said upright being provided withan arm on its lower end, on which a wheel, D, is placed.

To the upper end of the socket E there is attached a chain, G, whichpasses over a pulley, H, in the upper end of the upright F andunderneath a pulley, I, on the axle, and is connected at its inner endto a lever, J, the fulcrum-pin a of which passes through a bar, I),attached to the seat standards 0 c. To these same standards 0.0 there isalso attached a notched bar, K, to secure the lever J at differentpoints within the scope of its movement.

L is a bar, which is secured on the axle A at right angles, and has adraft-pole, M, attached to it, and N N are two beams, the front ends ofwhich are attached to the bar L by a pivot-bolt, O. The beams N N areparallel with the bar L, and they are connected by. cross-bars P. Eachbeam N has an inclined standard, Q, attached to it, and to thesestandards plows R. are attached, one plow being in advance of the other,so that the furrow-slices turned by the two plows may lap one over the Sis a bar, the rear end of which is connected by a staple, d, and rod 6with the plow-beams N N. This bar S extends up between the twoseat-standards c c, and has a longi'tudinalslot, f, made in it, throughwhich the upper part of a lever, T, passes, said lever having itsfulcrum-pin g in the rear part of the draft-pole M, and provided nearits lower end with a projecting arm, h, which has a chain, N", attachedto it, said chain passing underneath a pulley, O", on thedraft-pole,'and extending up to the front end of the bar S, to which itis attached, as shown clearly in Fig. 1.

On the front part of the bar S there is a hook, U, which holds the upperend of the leverT in the front end of the slotf, when necessary.

From the above description it will be seen that the driver from his seatV, by drawing back the lever T, may elevate or raise the plows out ofthe ground, and said plows retained in an elevated state by drawing theupper end of the lever T through a notch, "i, in the front of the seatand turning or running the latter a little to one side. The machine,with the plows thus held up, may be drawn from place to place or turnedat the ends of a field without any difliculty whatever. This elevatingof the plows may be assisted by the pressure of the feet of the driveron the front ends of the beams M. r

By adjusting the lever J the axle A may be more or less inclined to makethe plows conform to the surface of the ground over which they arepassing. By this means inclined or uneven ground will not affect theproper working of the plows.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent 1. The adjusting of the axle A, andconseqnently of the plow beams and plows, by means of the lever J,connected with the axle through the medium of the chain G, arrangedsubstantially as described, for the purpose of adjusting .the plows tosuit the surface of the ground over which they work.

. 2. The pivoted plow-beams N N, in connection with the bar S, lever T,and chain N", all arranged to operate in the manner substantially as andfor the purpose set forth.
